Try clearing the cookies for that site. That's the usual cause of request header too long errors. It can happen if a site is misconfigured and the cookie stored in your browser grows and grows over time.

Thanks Eliot - that is the website but your link is also blocked for me.
Deggles, If it is cookies - how do I clear them? I'm much better with spanners and hammers!
An idiots guide for clearing these cookies would be good.

In your internet browser in the settings section there will be a bit about deleting data/browsing history. In there you can then clear your cookies and cache.
